A crayfish eye is small and typically black in color. It has a compound structure with many tiny lenses that allow the crayfish to see movement and changes in light. They are located on stalks on either side of the crayfish's head.
Crayfish have compound eyes, which are made up of multiple individual visual units called ommatidia. Each ommatidium contains its own lens and photoreceptor cells, allowing crayfish to detect light and form images. This compound eye structure provides crayfish with a wide field of vision and the ability to detect motion effectively.
